During more than 30 years, as a collaborator with American, European and Latin American electronics magazines (*), has published a large assortment of practical circuits using common parts. In 1999 he included the first selection in a volume published by Prompt Publications in USA. The idea was to proceed with the series, publishing many volumes more. But, Prompt closed his activities and the idea was forgotten although the first volume became a best seller. Now with his own publishing house (NCB Publications) the author returned with the idea of make many volumes more of the series. So, the second volume is here proceeding with the same idea: give simple projects to the experimenters who want learn electronics using common parts and with no need of special knowledge about electronics. So, as in the first volume, many of the projects collected by the author are included in this volume, most of which you can build in one evening. The projects range from fun types through practical types to amusement types. Of course, there are other devices that can be used to teach you something about circuits and components. An important feature of theses projects are the ideas to Explore, intended for students looking for projects in science or to use in practical research. This ideal can be complemented by our book Science Fair and Technology Education Projects, also published in English by the author. We can consider this book as a source book of the easiest and fun-to-make of hundreds of projects created and published by the author during his life. (see more about Newton C. Braga in "about the author" in his site).
